Upstream oil and gas companies operate oil gathering systems comprising a flowline network and process facilities that transport the flow of produced fluids from the wells to a main processing plant. The frequency of corrosion related leaks has increased recently despite a corrosion inhibitor is injected at the wellhead into all flowlines. A root-cause analysis conducted by several companies revealed that severe internal corrosion was caused by a low fluid flow velocity an increasing water cut and the presence of sulfate-reducing bacteria (SRB) in the production streams. Nevertheless it was not clear why some of the flowlines may leak while others do not leak despite the composition of produced fluids principal design parameters (diameter and length) dosage of corrosion inhibitor and environmental conditions of the flowlines are similar. A diagnostic analysis of different oil flowlines of was carried out to gain an understanding of why a first group of oil flowlines is developing leaks and why a second group of flowlines has not experienced leaks. The methodology used for the diagnostic analysis comprises 1) Ultra-High Definition simulation of 3-phase or 4-phase flow of gas oil water and solids; 2) 3D imaging of phase distributions inside critical sections of the oil flowlines as per NACE ICDA; 3) mapping adverse operational conditions; and 4) the determination of probability of failure in the critical sections based on criteria depending on the severity of operating conditions inside and outside the flowlines. It was found that multiple sections were exposed to stagnant water and/or had a fraction of internal surface area covered by a stationary bed of solids (formation solids produced from the well). The identified causes of potential leaks comprise the following failure mechanisms: a) metal loss caused by colonies of SRB b) composed load acting on the pipe wall and c) cyclic" thermal expansion/contraction of the flowlines due to seasonal ambient temperature variations. One of the surprising findings of this study was that a shorter flowline with a lower water cut may have multiple leaks while a longer flowline with a higher water may not leak at all approximately for the same period after commissioning. This result was explained with help of maps of adverse operational conditions constructed for the two groups of flowlines. Immediate corrective mitigation actions and preventive actions were implemented to reduce leak frequency including the installation of a novel automatic flushing system.

Sour corrosion products could have a significant impact on the corrosion rate of carbon steel in H2S environments. It is widely believed that the different iron sulfides have different effects due to their distinct physico-chemical properties. Therefore an in-depth knowledge on the formation conditions of these polymorphous phases is of virtual importance for the understanding of sour corrosion process.Many studies have been performed to determine the key factors such as temperature solution pH H2S partial pressure and the duration of exposure in the formation of polymorphous iron sulfides; yet their formation conditions stability and phase relations are still not fully understood. This is partially due to the complex nature of sulfide and iron chemistry and their sensitiveness to oxygen. Seemingly minor changes in test conditions can often lead to dramatically different results.In this paper we present a statistic study on the corrosion products formed in some high temperature and high H2S gas wells in Saudi Arabia. Large numbers of deposits collected from downhole tubulars and wellhead manifolds are characterized for phase compositions. Results show a wide range of mineral phases and significant variation among the samples analyzed. The polymorphous iron sulfides include pyrrhotite pyrite marcasite troilite mackinawite and greigite in the order of abundance. Ferric iron compounds such as hematite magnetite akaganeite goethite and lepidocrocite are also identified in many samples. In addition ferrous iron products especially siderite are often detected. Based on the deposit structure analysis the formation mechanisms of these different types of corrosion products are discussed. It is hoped that the results from this work will contribute to further understanding of the sour corrosion process and provide value for corrosion and scale mitigation in oil and gas fields.
